Google says Gmail end-to-end encryption (E2EE) is now available on all Android and iOS devices, allowing enterprise users to read and compose emails without additional tools.
Starting this week, encrypted messages will be delivered as regular emails to Gmail recipients’ inboxes if they use the Gmail app.
Recipients who don’t have the Gmail mobile app and use other email services can read them in a web browser, regardless of the device and service they’re using.
Metformin is a first-line oral antidiabetic agent that has attracted increasing interest as a potential geroprotective therapy due to its ability to improve metabolic homeostasis, reduce oxidative stress, and attenuate chronic inflammation. However, its role in skeletal muscle aging and sarcopenia remains controversial. Observational and epidemiological studies suggest that metformin use is associated with a lower prevalence of sarcopenia, particularly in metabolically compromised or insulin-resistant older populations, where improvements in systemic metabolism and inflammatory burden may indirectly support muscle quality and function.

Bessières, Prikas, et al. report that episodic-like learning in infant mice establishes enduring memory schemas that guide adult behavior. The schema facilitates relearning and the formation of new, congruent memories in adulthood. Infantile schemas undergo hippocampus-dependent systems consolidation. While adult relearning relies on the PFC, the facilitation of new congruent memories requires PFC and top-down PFC-to-hippocampus neural projections.

George Church, Harvard geneticist and Human Genome Project pioneer, explains why CRISPR wasn’t the real breakthrough, how multiplex gene editing unlocked organ transplants and de-extinction, and why aging will likely require rewriting many genes at once.

Time may be viewed as an emergent consequence of increasing information entropy. I explore a toy quantum‑information model in which DNA is treated as an open quantum system. In this framework, weak, time‑dependent perturbations (potentially arising from thermal fluctuations, ionic microfields, metabolic noise, or electromagnetic signals) bias the micro‑timing of events during replication and repair. These slight timing shifts can influence the fate of transient electronic and protonic configurations (including short‑lived tautomeric states driven by proton‑transfer tunnelling), subtly altering mutation probabilities. To test this idea, I map nucleotides in the Mycobacterium tuberculosis genome to constrained qubit states and quantify informational structure using Shannon and von Neumann entropies and coding to non‑coding correlation metrics. Simulations of Hamiltonian dynamics under physiologically plausible perturbations show that real genomic segments exhibit distinctive dynamical signatures compared with controls. I also examine a variant in which a weak, slowly varying external signal is introduced as a background “beat” against which DNA dynamics can be compared. Because a Doppler shift in electromagnetic waves encodes the flow of time through the relative motion of source and observer, a cosmic microwave background (CMB) with a tiny frequency drift provides a conceptual clock and a source of informational entropy: it feeds a time‑correlated input into the DNA quantum system, allowing the molecule to sample cosmic time and translate it into a biological scale by modulating tunnelling probabilities and thus mutation patterns. This CMB‑inspired drive is simply a convenient illustration; the model does not rely on it, and other sources of weakly structured entropy could be tested. Across simulations, sequence‑dependent responses to both intrinsic and structured perturbations generate testable predictions: changing the structure or timing of these weak perturbations should produce reproducible shifts in mutation spectra. This framework connects cellular ageing and evolution to the flow of cosmic time and suggests experiments to probe DNA’s sensitivity to time‑dependent perturbations.

Though the point of a blog post like this is to get eyes on its event, it doesn’t just seem like lip service. Framework has been making modular laptops for years now, and even put out a desktop last year. Last year, the Framework 12 laptop got a 10/10 from iFixit regarding its repairability.
Framework says that every product it ships is in service of making computers “you can own at the deepest level and do what you want with.”
Framework, like almost every company, has been hit by the memory crisis. In January this year, it reportedly “held off as long as we could” but had to jack up the prices of its desktops and mainboards. And just this week, Framework said stabilising memory prices are simply a ‘temporary reprieve’ and that there would be more price increases to come in 2026.
The trillions of microbes living in the human gut are increasingly recognized as important partners in human health. Scientists have linked the gut microbiome to several aspects of health, from metabolism and immunity to mental health.
A recent study suggests that these microbes may also influence an important aspect of fitness—muscle strength.
Muscle strength is a crucial feature of health for many reasons. It supports our joints and keeps our bones healthy, boosts athletic performance and even plays a role in metabolic health.
A scorching “lava world” once thought barren may actually be wrapped in a thick, mysterious atmosphere. Astronomers have uncovered surprising evidence of a thick atmosphere surrounding TOI-561 b, a scorching, fast-orbiting rocky planet once thought too extreme to hold onto any gas. Using NASA’s James Webb Space Telescope, researchers found the planet is far cooler than expected for a bare rock, hinting at a heat-distributing atmosphere above a churning magma ocean. This strange world—where a year lasts just over 10 hours and one side is locked in eternal daylight—may even be rich in volatile materials, behaving like a “wet lava ball.”
A team of astronomers led by Carnegie has uncovered the clearest evidence yet that a rocky planet outside our Solar System has an atmosphere. Using NASA’s James Webb Space Telescope (JWST), the researchers identified signs of gas surrounding an unusual target: an ancient, extremely hot super Earth that likely has a surface covered by molten rock. The findings were published in The Astrophysical Journal Letters.
The planet, known as TOI-561 b, has about twice the mass of Earth but is dramatically different in almost every other way. It orbits extremely close to its star, at a distance just one fortieth that of Mercury from the Sun. Even though its star is slightly smaller and cooler than our Sun, the planet’s tight orbit means it completes a full year in only 10.56 hours. One side constantly faces the star, leaving it locked in permanent daylight.
